Forwarding to your ISP

[Pedro Marques]

IMHO forwarding dns requests has some advantages, such as reducing hops
between client and server, saving international bandwidth (very important in
some countries) and you don't need to update the root servers file anymore
;) ... some disadvantages are any downtime,load or problem your ISP DNS may
have or the cache you can't control (or flush) when you need it.

I think that if you have a fast and reliable Internet connection, you can
query root nameservers directly, if not, you may consider using your ISPs as
NS.

It's up to each one decide what's best in each case.

Just my opinion,

Pedro
